How much land does it take to support a human being? Boundaries of China superimposed upon those of the USA. Let's do the math again, but this time for the entire planet. The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous. Subtracting this uninhabitable 57% (32,665,981 mi2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land.
Written By: Acre, unit of land measurement in the British Imperial and United States Customary systems, equal to 43,560 square feet, or 160 square rods.
